Hi …my green beans are in a raised garden. The garden is covered with a greenhouse type zip up cover. Would that cause them to not get enough light? Also…everyplant is yellow but one. The one is thriving. Makes me think its not a sunlight thing???

In reply to Ila.

Hi Ila, are you practicing crop rotation? There are various bacterial and fungal diseases that affect beans. Planting them in a different spot helps reduce the risk of re-infection. Other than that I would also suggest planting the seeds at least 6 inches apart to increase air flow around and through the plants. This helps if disease is the problem. Good luck!! Niki

It’s my first year w raised beds. My green beans leaves are a bright yellow. The 12” bed has a base of twigs, then a layer of organic “raised bed potting soil.”

It’s been dry around here except for some heavy periodic rains. Rainfall is still below average.

Hi Kimberley, It could be the sawdust. Sawdust can be used as a mulch on top of the soil, but adding it into a bed can draw nitrogen away from the plants. The sawdust uses the nitrogen as part of the decomposition process. Plants that are nitrogen deficient often turn yellow. Time will break the sawdust down and reduce this problem. You can also supplement nitrogen by adding a fertilizer high in nitrogen. Good luck! Niki

I bought my dwarf beans as plants which looked healthy at the time. I have just built my raised vegetable garden so this is the first time of growing in it. I started with cardboard then sawdust, torn newspaper, old leaves, mulch, and lastly topsoil. The soil was from my property. I planted them in August and we have had a lot of rain but also sunshine. They are in full sun and have no obvious disease or pests attacking them. Is it just the cold weather?
